Just one I didn’t see on here yet:
Each kid gets an Alka-seltzer that has been pre-drilled and put onto a string. They must wear it like a necklace. The each kid either gets a styrofoam cup or a squirt gun depending on how you play. Split the kids into two teams or play every man for himself. The object is to melt the opponents tablet first, thus they are out when the tablet falls off the string. The tables must be in full view and cannot be touched.
At the boundary (whatever you determine) corners place 5 gallon buckets full of water or trashcans full of water (which ever work best for your version) to refill. This is a fun one that can be short or a longer game depending on how it’s played. Make sure the kids wear clothes that can get messy because the depending on the flavor you bought or the alka-seltzer itself, sometimes there is a stained area still left after washing!!
